Experts on Ceres

Ceres (/ˈsɪərz/;[16] minor-planet designation1 Ceres) is the largest object in theasteroid belt, which lies between the orbits of Mars and Jupiter. Its diameter is approximately 945 kilometers (587 miles),[6] making it the largest of the minor planets within the orbit of Neptune. The thirty-third largest known body in theSolar System, it is the only one identified orbiting entirely within the orbit of Neptune that is a dwarf planet.[17] Composed of rock and ice, Ceres is estimated to comprise approximately one third of the mass of the entire asteroid belt. Ceres is the only object in the asteroid belt known to be unambiguously rounded by its own gravity. From Earth, the apparent magnitude of Ceres ranges from 6.7 to 9.3, and hence even at its brightest, it is too dim to be seen with the naked eye, except under extremely dark skies.
